120MEA-SG, 256-MEA-SG, ME-W-SG
The produces sine waves or real signals in digitized form. These signals are detected as analog signals with
the MEA-System. Because of this data source you are able to use and to test the complete MEA-System.
Each MEA-SG operates in a similar way to the standard MEA probe, but without a biological object.
It is possible to simulate 12 different types of signals. Furthermore MCS offers the possibility to program
individual signals on special request. Please contact Multi Channel Systems MCS GmbH if this is required.
The base of a MEA-SG is made of printed circuit board. It shows the MEA standard design,
the square recording area surrounded by gold contact pads. Instead of electrode arrays in the middle,
there is a battery for power supply, a blue double DIP switch, a plug socket for grounding cable, a control
button, and a LED.
To start a MEA-SG press the control button. To stop it, press the button for longer than two seconds.
A flashing LED indicates activity. The position of the DIP switch selects different categories of signals (see
table below).
Important: To change DIP switch position, please switch off the device!
By pushing the control button it is possible to select the desired waveform of that category.
For example: Set the DIP switch to switch 1 ON and switch 2 OFF and activate the MEA-SG
by pressing the control button. The generator now produces EPSPs. Press the button again,
and the generator switches to pop spikes, to spikes and back to EPSP and so on.
To save battery power, the MEA-SG will run a desired signal for the duration of one hour and then switch
off automatically.
